World Fantasty Award for Best Novel. It's a controversial win - the book is harrowing and horrible, and the bittersweet ending is far more bitter than sweet, but it is also utterly compelling. Wonderful news!
I first came across Margo Lanagan on the way to the 2006 BFS Fantasycon in Nottingham, when I read her second collection Black Juice in one sitting. I'm looking forward to finding out more about the novels she wrote before which still don't seem to be readily available in the UK but do appear on her Wikipedia page
